(optional) If specified, appends this text to the end of every mailing list message.
When you create a mailing list, Lyris defaults to putting a footer at the bottom of every message which tells the recipient what email address they are subscribed with, and how to unsubscribe.
The text of the default footer is:
--- This footer uses the mail merge fields to allow failsafe unsubscribing. See How can I use the Mail merge feature?.
You are currently subscribed to $subst('List.Name') as: $subst('Recip.EmailAddr')
To unsubscribe send a blank email to $subst('Email.UnSub')
Of course, you can change this footer to be anything you like, or remove it completely.
